本研究應用相位平移輪廓法於血糖儀電極高度資訊重建，因血糖儀電極採用沖壓模之方式製造，其表面會有沖頭擠壓後之凹陷，為了解其血糖儀電極之凹陷變化程度，以得知血糖儀電極與血液接觸資訊，故需重建血糖儀電極高度資訊。
本研究提出改良式數位正弦條紋產生公式，改善傳統過渡曝光之問題，並結合田口方法來找出其最佳水準值，產生條紋亮度對比度較高的數位正弦條紋影像，再利用亮度校正方程式改善投射角度與參考平面具有偏斜，會造成其亮度偏差之問題。本研究藉由數位光處理(digital light processing, DLP)投影機進行投影並分析進行其高度資訊重建，其量測精確度為0.008mm；還使用彩色影像處理技術，產生不同色彩正弦條紋影像，找出適合血糖儀電極之色彩正弦條紋影像，經由實驗分析後，使用黃色數位正弦條紋來進行血糖儀電極之高度資訊重建，能突顯血糖儀電極表面相位資訊，進而重建精確血糖儀電極高度資訊。本研究使用相位平移輪廓法於血糖儀電極高度量測，可得知其高度變化資訊，以提升血糖儀量測血糖值之準確性。

This study applied the phase shifting profilometry method in the height information reconstruction for electrode of glucose meter. Since electrode of glucose meter is produced by using the stamping die manufacturing, its surface may have punch extrusion depression. The electrode of glucose meter height information needs to be rebuilt to demonstrate the depression change level of the electrode of glucose meter, and acquire the information of the contact between the electrode of glucose meter and blood.
This study proposed the improved sinusoidal fringe formula to improve the traditional transitional exposure, and found the optimal levels by integrating the Taguchi method to produce digital sinusoidal fringe image of strip brightness of high contrast. The brightness correction equation was employed to improve the projection angle and the reference plane divergence, which may result in the problem of brightness deviation. This study used the DLP (digital light processing) projector for projection and analysis to reconstruct the height information. The measurement accuracy is 0.008mm. The color image processing technology was used to produce different color sinusoidal fringe images to identify suitable color sinusoidal fringe images for the electrode of glucose meter. According to the experimental analysis, using the yellow digital sinusoidal fringe for the height information reconstruction of the electrode of glucose meter could highlight the electrode of glucose meter surface phase information, and further reconstruct the accurate electrode of glucose meter height information. This study application the phase shifting profilometry method in electrode of glucose meter height measurement, and obtained height change information to improve the accuracy of blood glucose meter in the measurement of the blood glucose level.
